The export option allows one, or more, pipe networks from within the Civil 3D® design to be exported to an .IDDX file ready for use in InfoDrainage.

If a network was original created from an InfoDrainage design it will attempt to maintain features such as Stormwater Controls and channel connections that have been imported as other elements during the Import. This allows a design to be adjusted within Civil 3D® and then saved back to InfoDrainage for further design work and/or hydraulic analysis without the loss of information.

Export Wizard

There is a wizard to guide the user through the export process. The wizard presents the user with a sequence of dialog boxes that lead the user through a series of well-defined steps. To progress through the steps in the wizard, press the Next button. To return to a previously completed step, press the Previous button. 

Step 1: File Selection

This step allows the selection of the file to be written to. Pressing the select button invokes a file selection dialog to allow easy location of the file/folder.

Step 2: Network Selection

This step allows the selection of pipe networks that will be exported to InfoDrainage. Each selected network will be exported as a phase.

Surfaces

There are three surface export options that can be selected on the Network and Surfaces step during the export from InfoDrainage.

Create surface from cover levels - A surface will be created for the Phase using the Pipe Network levels as well as stormwater control outlines and exceedence levels.

Do no export surface - No surface is provided for the phase during the export.

'Surface Name' - Export the surface that is currently referenced by the Pipe Network.


Step(s) 3 till end: Parts Mapping

For each selected network there will be a parts mapping step, which allows the mapping of Civil 3D® part types to InfoDrainage types. See Parts Mapping for more details. 

When the step is initially shown, the network to be exported is examined. If any network parts are discovered that have no current mappings, a blank entry will be added for that part type.

When Next or Finish is pressed at each parts mapping step the given parts mappings will be validated. Any invalid properties will be flagged and will need correcting before the step can be completed.


Note

Where InfoDrainage items have been imported but do not map to Civil 3D® parts, they can be added to the mappings to specify that we do want to export those InfoDrainage types. Please see Representation of Unsupported Data for more information

Export Warnings

The following table lists some common Export Warnings you may encounter when exporting to an InfoDrainage file.

Civil 3D® ItemWarning
Inlet Null StructureCivil 3D® pipe starts from an inlet structure, the pipe has been converted to a Bypass connection.
Inlet or Outlet Null StructureStructure has been moved outside the boundary of the linked Stormwater Control; this has been moved within the boundary.
Outlet Null StructureStructure has more than one outgoing connection; a duplicate outlet has been created for this connection.
Outlet Null StructureStructure has an incoming connection; an inlet has been added for this connection.
